Answer 1

Question :

find the curved surface area and total surface area of a cylinder the diameter of whose base is 7 cm and height is 60 CM

To find :

Curved surface area and total surface area of cylinder

Solution :

Diameter of cylinder = 7

radius of cylinder = 7/2 cm= 3.5cm

Total surface area of cylinder

2πrh + 2πr²

2πr(h+r)

=2×22/7×3.5(60+3.5)

= 2×22×0.5×63.5

= 1397cm²

Curved surface area of cylinder

2πrh

= 2×22/7×3.5×60

= 2×22×0.5×60

= 1320cm²
